Proverbs 25:21

If thine enemy be hungry, give him bread to eat Which includes all manner of food; whatever persons may have in their houses, that they should bring out and feed the hungry with, even though an enemy; and if he be thirsty, give him water to drink; which was what was usually and in common drank in those countries. These two, bread and water, take in all the necessaries of life; and giving them is expressive of all acts of beneficence and humanity to be performed to enemies; see ( 2 Kings 6:22 ) ; or "drink to him", so Pagninus and Montanus; which is still more expressive of respect and kindness.
